ABSTRACT
In this study, to identify single nucleotide polymorphisms (SNPs) associated with meat quality in Berkshire pigs, we performed RNA sequencing. A non-synonymous SNP (nsSNP) in the Complement component 9 (C9) gene was identified, and the association between meat quality traits and the C9 genotype was analyzed. The nsSNP in the C9 gene was located at c.942 G >T. In the dominant model, significant associations were observed between the SNP and meat quality traits such as CIE L, collagen content, moisture level, and pH24 h, whereas in the co-dominant model, significant associations were observed between the SNP and CIE L, collagen content, and protein content. In the recessive model, a significant association between the C9 genotype and the collagen content was observed. In addition, we identified the significant relationship between the C9 genotype and meat quality according to sex. These results indicate that the C9 SNP can be used as a genetic marker for improving pork quality.
